Specification of Iietters Patent. Patented Feb. 18, 1913,

Application filed August 21,1911. Serial No. 645,264.

To all whom. it may con ern:

lie it known that l. (imunns S. Locuwoon, a citizen of the UnitedStates, residing at 289 Market street, Newark, county of Essex, andState of New Jersey, have invented certain new and useful Improvementsin Thrust-Rings, fully described and represented in the followingspecification and the accompanying drawings, forn'iing a part of thesame.

This invention relates to that-class of thrust-bearings which is formedas a loose ringto encircle a shaft between the parts subjected "tothrust, and the invention is especially applicable to such a thrust-ringcarrying a series of spirally wound rolls. Iii-such rolls the ends ofthe strand forming the 'roll ta ')er off to a chisel edge at each end ofthe roll, and are thus liable to chafe or abrade the metal of thethrust-ring at the end of the socket inclosing the roll, whenever theroll from any cause presses endwiscdn its socket.

flhe objects of the present invention are, fir t, to furnish a cheapconstruction for the roll-carrying ring,by which it may be formed (withsuitable roll-sockets) of relaof steel. and hardened The invention willbe understood by reference to the annexed drawing, in which Figure 1 isa side view of the complete thrust-ring with one of the rolls omitted;Fig. 2 is a section of the same on line-EZ- Z in Fig. 1; Fig. 3 is anend .view and Fig.4 a side View of a spirally wound roll; F ig. 5 showsthe inner sideof one of the ringplates; Fig.6 is a section on line 6 inig. 1; Fig. 7 is a side' view, Fig. 8 an edge View of one of the wearingpieces, Fig. 9 shows an alternative construction.

In Figs. 1 to 9 inclusive, the ring is shown with apertures forming tenradial sockets a to carry ten cylindrical rolls 7), the ring beingdivided into two similar ring-plates f at the center of the rolls, and

the half-sockets in such plates concaved in sides of the rolls projectfrom the sockets upon both sides of the ring. To make the ring-plates fcheaply, I for them of alloy (as type metal) that can be readily cast ina metal die, and thus secure accuracy of shape and suitable finishWithout any machine-work upon them; but by such mode of constructionthey are necessarily much softer than the hardened rolls, and veryliable to abrasion by the chiselshaped end of the spirally wound rolls.

There is a great demand at t-he present time for so-called high dutyhearings in which a small bearing is adapted to sustain a heavy load bymaking the rolls of hardened steel. Such steel rolls are very unyieldingif made of solid steel, and I have therefore devised the bearing withthe tubular spirally wound rolls, which possess thus enabled to resistwear most perfectly.

In Figs. 2 and 4, the roll is shown formed' of. a spirally wound strand,which terminatcs ateach end of theroll in a bevel or chisel-shaped end6, and if such a roll be made of hardened steel, the ends I) would becapable of grinding or Wearing into the metal at the ends of theroll-socket; and this is prevented by the stationary wearing-pieces.

Notches r: are shown formed in the four corners of each half-socket, toreceive lugs d on the ends of the flat wearing-pieces e, which areshaped, as shown in'Fig. 7 'to fill or cover the ends of the socket, andthus hold the ends of the rolls from contact with the formed in the tworing-plates in which the wearing-pieces are fitted before the halvesofithe ring-plates are secured together by the screws g. By thisarrangementthe wearingpieces are held in place by the curved sides ofthe half'sockets and are enabled to ex tend across the joint of thering-plates and thus whollyprotect the ends of the sockets irom wear.The fastening of the ringplates together serves to hold thewearingpiecespositi'vely within the-sockets end thus reventstheirdisplacement in the siightest egree. As such wearing-pieces can beStamped from sheet-metal and tempered in batches, they furnish a vverycheap pr'otec tion for the ends of the socket. If they were 10 permittedto rotate in the sockets the would wear the sockets seriously when t erolls pressed endwise, but their stationary char-.

' rolls are divided transversely, and a weari ng-piece e insertedbetween their adjacent ends. This construction permits the outer sectiona of the roll to rotate faster than the inner one a ,'as required by itsgreater dis-' tanoe from the center of the-thrust-ring; "while thewearing-piece e prevents the sections of the roll from abrading oneanother. This piece e may be held stationary "by. the same means as thepieces e.

' Having thus set forth the nature of the invention what is claimedherein is:

f1. A thrust-ring having two ring-plates with. correspondinghalf-sockets in each,

'rollsjfitted toturn. in the sockets and projected from the oppositesides of the ring, and fiat wearing-pieces fitted within the ends of thesockets adjacent the ends of the rollsand held from turning in thesockets rally wound rolls in the said sockets, and fiat wearing-piecesfitted between the ends of the rolls and sockets and held from turningtherein and extending across the joint of the ring-plates.

3. A thrust-ring formed of two similar soft metal ring-plates f havingcorrespond ing half-sockets a therein with notches c in the innercorners, rolls fitted to the sockets, wearing-pieces having lugs 03fitted to the said notches to hold the wearing-pieces from turning andmeans for securing the ringplates together with the rolls in the socketsand thewearing-pieces extended across the joints of the ringrplates.

4. A thrust-ring having two ring-plates with corresponding half-socketsin each, rolls fitted to turn in the'sockets and divided transverselyinto sections and pr0- jected from opposite sides of the ring, flatwearing-pieces fitted to eachsocket between the adjacent ends of theroll-sections, and wearing-pieces within the ends of the sockets, thewearingpieces being held from turning in the sockets and extendingacross the jointof the ring-plates.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
